The present invention relates to a lighting device for automobile headlights, comprising two or more lighting units arranged next to each other, where each lighting unit has:

- one or more light sources and

- one transparent primary optical device assigned to said one or more light sources,

- and includes one transparent secondary optic,

In this case, the primary optical device of each lighting unit divides the light emitted by one or more light sources assigned to the primary optical device in such a way that one or more light distributions are generated by the secondary optical device of the lighting unit. designed for deflection towards secondary optics, wherein the lighting device has a fixing element for fixing the primary optics of the lighting unit, wherein the fixing element is formed by a body made of a transparent material, wherein: The body is provided with receiving through openings located next to each other, each of the receiving through openings having one primary optical device arranged therein, wherein the primary optical device is one of the receiving through openings facing towards the adjacent receiving through opening. Each is mounted on one or more limiting surfaces, wherein the receiving through openings are spaced apart from each other.

Regarding the directional indication used, it starts from the assumed arrangement of the lighting device in a horizontal position. In this regard, the designation “side by side” means “side by side.” In other arrangements, for example an arrangement rotated by 90°, the expression “next to each other” may also be understood to mean the same thing as “overlapping above” or “overlapping down”.

Additionally, the present invention is also related to automobile headlights including such lighting devices.

It is used to create , and in this case, it is also possible to realize a combination of lighting functions.

For fixing the primary optics of two or more lighting units, fixing elements are provided that are designed to be transparent, in particular to be light-transmissive and/or light-conductive. Such a design makes it possible, for example, to manufacture the primary optical device and the fastening element together in one injection molding process.

At this time, so-called missing light, that is, light from a light source that is undesirably combined into the holder through its primary optical device, is propagated by total internal reflection within the holder and is emitted again in an unwanted location. It can be. For example, light from the light source of the first lighting unit may exit the area of the second lighting unit and enter the external space through the secondary optics of the second lighting unit, in which case this situation may occur in the area of the second lighting unit. may cause a negative impact on the light distribution produced by.

The task of the present invention is to prevent or reduce light coupling into the fastening element.

The above problem is the lighting device mentioned in the preface, wherein according to the present invention, an over-coupling prevention device is arranged in the body between two receiving through openings located next to each other, wherein the over-coupling prevention device is located within the body. formed from a through opening, in this case the through opening of the anti-coupling device is limited by two sides, which face towards the receiving through opening in which the primary optics are arranged, and in this case the sides One or more of the side(s), i.e. the very side(s) on which the opposing limiting surfaces of one receiving through aperture are contacted by the primary optics arranged in the receiving through aperture, are addressed by providing light deflection means, wherein This light deflection means deflects at least part, and preferably all, of the light rays that enter the body from the primary optic, which is directed towards the side and is in contact with the opposing limiting surface, and impinges on the side, thereby deflecting part of said light ray. It is designed so that it does not enter the adjacent lighting unit or collide with the secondary optics of the adjacent lighting unit.

For example, the primary optical device is in direct, especially planar contact with the limiting surface(s) or is provided with a contact element that realizes the connection, as explained further below.

Preferably, it can be proposed that the fixing element and the primary optical device are designed as one piece, preferably made of the same material.

Preferably, it is proposed that the primary optical device contacts the stationary element at exactly one limiting surface, in particular facing it.

In this case, the upper and lower limiting surfaces of the receiving through opening are not provided with contact, which avoids the situation where scattered light is coupled into the interior of the fastening element via these limiting surfaces.

In particular, designing light deflection means to deflect impinging rays in such a way that the deflected rays have a larger up/down-component (z-component) than the impinging rays, and/or to separate the impinging rays into individual lighting units. It may be proposed to design the light deflection means to deflect opposite to the direction of light emission.

In this case, the direction indication is related to the assumed arrangement of the lighting device in a horizontal position as described in the introduction. In an arrangement rotated based on this assumed arrangement, the direction naturally changes correspondingly. For example, in an arrangement rotated 90°, it changes from top/bottom components to left/right components.

Accordingly, the rays are deflected more strongly either upward or downward, and either propagate within the fixed element, or upward or downward from the fixed element to such an extent that the ray does not impinge on the secondary optics or, in principle, enter the interior of the adjacent lighting unit. And it is discharged upward/downward.

Particularly preferably, it is proposed that the light deflection means comprise at least one light deflection surface, which ensures that impinging light rays do not enter the interior of an adjacent lighting unit or that of the secondary optics assigned to the adjacent lighting unit. Deflect the impinging light rays in such a way that they do not impinge on the area.

Particularly preferably, in this case the light rays are generally deflected in such a way that they are not deflected forward, and consequently cannot reach the secondary optics of adjacent secondary optics.

It may be proposed that the primary optics of two or more lighting units each have a main light emission direction, in which case, for example, the main light emission directions are aligned in substantially the same direction, in particular parallel to each other. Sorted.

It may be proposed that the sides of the overcoupling prevention device run parallel to the main emission direction of the primary optics of each adjacent lighting unit.

It may be proposed that the sides of the overcoupling prevention device run vertically.

For example, it may be proposed that the light deflection means are designed in the form of grains, contain grooves or are designed in the form of grooves, in which case the grooves preferably extend in the horizontal direction, In particular it extends in the direction of the main light emission direction of the primary optics of the adjacent lighting unit.

For example, the grooves are straight grooves, thereby extending along the longitudinal direction of the straight line, and preferably the grooves that lie next to each other are parallel to each other.

The grooves can be formed, for example, in the form of a triangle, in the form of a partial circle or semicircle, in the form of a prism, in the form of a round shape, etc., when viewed in a cross-section, especially in a cross-section perpendicular to its longitudinal direction.

It may also be proposed that at least one of the primary optical devices, preferably each primary optical device, comprises at least one projection optical element, in which case preferably when two or more projection optical elements are present, these Projection optical elements are arranged in one or more rows.

Each of these projection optical elements can be designed as a unique projection lens.

Each projection optical element can produce a unique part of the light distribution of the illumination unit, for example a light segment.

The projection elements can be directly adjacent to each other and are preferably rigidly connected to each other, in particular formed in one piece and particularly preferably made of the same material.

The rows run horizontally and transversely, in particular at 90° to the direction of emission (X1, X2) of the individual lighting units.

By means of one or more external projection optical elements, the projection optics device is connected to the stationary element.

More preferably, it may be proposed that the at least one primary optical device is in contact with the at least one limiting surface via a wedge-shaped contact element arranged between the limiting surface and the primary optical device, and in this case further contact elements of the contact element. The narrow wedge surface contacts the primary optic and the opposing wider wedge surface contacts the limiting surface.

The contact elements are preferably made of the same material as the fastening elements and the primary optics; Preferably the fastening element, the contact element and the primary optical device are formed integrally with each other.

The use of such contact elements further contributes to the reduction of scattered light, since in this way the area where the projection optics are connected to the holder can be kept small in size and, consequently, less likely to pass through light. In this case, excellent stability of the connection can be ensured at the same time.

In this case, the contact element or contact elements can be particularly geometrically designed in such a way that the light is deflected backwards, i.e. away from the secondary optics and/or separation of the light from the contact element/contact elements is prevented. It can be designed especially geometrically in such a way that

It can be proposed that at least the light source of the lighting units, in particular the light source of each lighting unit, is designed as an LED or is of the light-emitting diode type, wherein if a plurality of light sources are provided, these light sources are preferably arranged in one or more rows. .

The rows of light sources are assigned to the rows of primary optics, for example in such a way that each projection optical element is assigned at least one light source/LED, preferably exactly one light source (LED), in which case preferably The assigned light source/LED is exclusively assigned to only the one projection optical element.

The light source of one lighting unit can preferably be triggered independently of the light source of the other lighting unit.

Preferably, the light sources of one lighting unit can be triggered independently of other light sources of this lighting unit, or a group of light sources of one lighting unit can be triggered independently of other groups of light sources of this lighting unit.

The primary optical element is for example a lens, in particular a biconvex lens.

The light sources, in particular LEDs, are preferably each - when viewed in the direction of light propagation - in front of the focus of its own primary optical element and are imaged in an enlarged manner, in which case the image of the light source is in particular a virtual image.

The secondary optical device is preferably arranged in such a way that its own focus is created substantially within a magnified image - in particular a virtual - of the light source, in particular the LED, formed by the primary optical element.

For example, the secondary optics are projection optics.

It may be proposed that the one or more projection optical devices or the projection optical elements of the one or more projection optical devices are formed to be biconvex.

This bi-convex design has been found to provide additional protection against scattering because when light enters through the convex entrance surface, light bundles enter the optical device in the form of bundles, resulting in This is because the bundle can no longer bind too strongly to adjacent optical devices.

It is preferred if the secondary optical device is designed as a secondary optical device component.

The secondary optical device is thus implemented as a single component with different optically effective areas (= secondary optical device), preferably each with (exactly) one effective area per illumination unit.

It may also be proposed to arrange a screen between two or more lighting units, in particular a wall-shaped screen, which extends from the stationary element to the secondary optics.

One screen or a plurality of screens and fastening elements preferably have upper and lower parts that can be inserted together, overlapping one another.

For example, the screen is in contact with the fastening element 100 , and as a result the light originating from the lighting unit cannot cross the gap between the screen and the fastening element and enter the interior of the adjacent lighting unit.

One or more screens run approximately parallel to the main light emission direction of adjacent lighting units, or parallel to each bisector of the main light emission direction of two adjacent lighting units.

The one or more screens are particularly flat and run substantially vertically.

Below, the structure of the exemplary lighting device 100 according to the present invention is first described in more detail with reference to FIGS. 1 to 5 .

The lighting device 1 includes two or more, in a specific example, four lighting units 10 and 20 arranged side by side. Each lighting unit (10, 20) is

- one or more light sources 11, 21 ( Figure 4 ),

- transparent primary optics (12, 22), assigned to one or more light sources (11, 21), and

- It also includes transparent secondary optical devices 31, 32.

In the example shown, the primary optical devices 12 each comprise exactly one primary optical element 12a, and the primary optical devices 22 each comprise a plurality of primary optical elements 12a arranged next to each other in one horizontal row. It includes an optical element 22a. Preferably, the four primary optics 12, 22 are likewise arranged in one row.

The rows run horizontally and transversely, in particular at 90° to the (main) emission direction (X1, X2) of the individual lighting units (10, 20).

Each of these primary optical elements 12a, 22a can be designed as its own projection lens.

It may be proposed that the primary optical elements 12a and 22a are formed in a biconvex shape.

The light sources 11, 21 are preferably designed as LEDs, in which case each primary optical element 12a, 22a is preferably assigned a unique LED 11, 21. Each LED 11, 21 together with its primary optical element 12a, 22a can produce an image of the light source, in particular an enlarged image, for example in the form of a light segment.

The primary optical elements can be directly adjacent to each other, and are preferably rigidly connected to each other, in particular formed in one piece, particularly preferably made of the same material.

The light source of one lighting unit can preferably be triggered independently of the light source of the other lighting unit.

Preferably, the light sources of one lighting unit can be triggered independently of other light sources of this lighting unit, or a group of light sources of one lighting unit can be triggered independently of other groups of light sources of this lighting unit.

The light sources, in particular LEDs, are preferably each - when viewed in the direction of light propagation - in front of the focus of its own primary optical element and are imaged in an enlarged manner, in which case the image of the light source is in particular a virtual image.

The secondary optical device is preferably arranged in such a way that its own focus is created substantially within a magnified image - in particular a virtual - of the light source, in particular the LED, formed by the primary optical element.

For example, the secondary optics are projection optics.

In the example shown, the secondary optical devices 31 and 32 are designed as secondary optical device components 30 . The secondary optical device is therefore implemented as a single component with different optically effective areas (= secondary optical device), preferably each effective area per lighting unit.

The primary optical devices 11, 22 of each lighting unit 10, 20 deflect the light emitted by the light source 11, 21 assigned to them to the secondary optical devices 31, 32, The secondary optics 31, 32 of the lighting units 10, 20 are designed to produce one or more light distributions. For example, the light emitted by the light source to the primary optics is then transmitted as a (partial) light distribution by the primary optics together with the associated secondary optics in the far field, i.e. on the road, for example. It becomes an image. In this way, all light sources of one lighting unit together form the (total) light distribution.

Examples of such light distributions or corresponding light functions are:

ADB(눈부심 없는 하이 빔),

ADB (Anti-glare high beam);

AFS(로우 빔 모드 및 눈부심 없는 하이 빔 모드에서의 코너링 라이트), 또는

AFS (cornering lights in low beam mode and glare-free high beam mode), or

정적 시스템(에이프런, 정적 하이 빔).

Static systems (apron, static high beams).

The lighting device 1 also has a fastening element 100 that fastens the primary optics 12 , 22 of the lighting unit 10 , 20 . The fastening element 100 is formed by a body 110 made of a transparent material, which has receiving through-openings 101 and 102 located next to each other, in which the primary Optical devices 12 and 22 are respectively arranged.

Preferably, the fastening element 100 and the primary optics 12, 22 are formed as one piece, preferably made of the same material.

Each primary optic 12, 22 is connected with one or more limiting surfaces 101a, 101b, 102a, 102b, respectively, of the receiving through openings 101, 102, in particular with the lateral limiting surfaces. Preferably, each primary optic 12 , 22 is connected to two confinement surfaces opposite one another, preferably lateral, wherein in a specific example the primary optic 22 is one of the confinement surfaces 102a, Connected to 102b), the primary optic 12 is connected to confinement surfaces 101a, 101b. The primary optics are spaced apart from the upper and lower limiting surfaces, respectively. In this case, in the case of a primary optical device 22 with a plurality of primary optical elements 22a, the connection to the fixing element is preferably made at one or more or external primary optical element(s).

In order to enable a stable connection, the contact area between the primary optic and the limiting surface is provided with a specific extension/surface through which light can enter the holder interior, preferably Unrelated scattered light may, for example, enter the interior of an adjacent lighting unit.

Therefore, in the example shown, the light of the projection optics 12 of the lighting unit 10 will enter inside the fastening element 100 or body 110 through the limiting surface 101a of the receiving through opening 101. This may lead to undesirable scattered light entering the adjacent lighting unit 20.

Likewise, the light of the projection optics 22 of the lighting unit 20 can enter the interior of the fastening element 100 or the body 110 through the limiting surface 102b of the receiving through opening 102 and thereby into the adjacent Undesirable scattered light may be introduced into the lighting unit 10.

Therefore, according to the present invention, an overcoupling prevention device 200 is arranged between the two receiving through openings 101 and 102 located side by side within the body 110. In this case, the overcoupling prevention device 200 ) is formed from a through opening 201 in the body 110, where the through opening 201 of the overcoupling prevention device 200 is limited by two sides 211 and 212, and these sides ( 211, 212 are directed towards the receiving through openings 12, 22, where the primary optics 12, 22 are arranged.

The sides (211, 212) are provided with light deflecting means (220, 230), which are directed towards the sides (211, 212) and are in contact with a limiting surface facing the sides (211, 212). By deflecting at least part, and preferably all, of the light rays that enter the body 110 from the primary optical devices 12 and 22 and impact the sides 211 and 212, the parts of the light rays are connected to adjacent lighting units. (10, 20) It is designed so that it does not flow into the interior or collide with the secondary optical devices (31, 32) of the adjacent lighting units (10, 20).

As can be seen in Figure 7 , light deflection means 220, 230 are provided to deflect the impinging light rays, preferably in such a way that the deflected light rays have larger up/down-components (z-components) than the impinging light rays. ) was proposed to design.

Accordingly, the rays are deflected more strongly either upward or downward, and either propagate within the fixed element, or upward or downward from the fixed element to such an extent that the ray does not impinge on the secondary optics or, in principle, enter the interior of the adjacent lighting unit. And it is discharged upward/downward.

Alternatively or preferably additionally, the light deflection means (220, 230) is designed to deflect the impinging light rays opposite to the direction of light emission (X1, X2) of the individual lighting units (10, 20) ( Figure 6 ) was also preferably proposed.

In particular, in this case, it may be proposed that the light deflection means 220, 230 comprise at least one light deflection surface 221, 231, on which the impinging light rays are adjacent to the illumination unit 10, 20) light rays that do not enter the interior or impinge on the area of the secondary optics 31 , 32 assigned to the adjacent lighting units 10 , 20 , and preferably on the sides 211 , 212 deflects the impinging light beam in a manner that has the deflection behavior described above.

The sides 211, 212 of the over-coupling prevention device 200 lie, for example, vertically, and the main light emission directions (X1, ) are each parallel to each other.

For example, the side surfaces 211 and 212 of the overcoupling prevention device 200 are in principle formed as flat surfaces, and the light deflection means 220 and 230 are formed on these surfaces, resulting in the side surfaces being It breaks away from the flat shape.

For example, it may be proposed that the light deflection means 220, 230 comprise grooves or that the bottom surface is formed in the form of a groove, in which case the grooves preferably extend in the horizontal direction, in particular adjacent lighting units ( 10, 20) extends parallel to the main light emission directions (X1, X2) of the primary optical devices 12, 22.

As can be seen in each figure, the primary optics 22 are directly connected to the confinement surface 102b, that is, the outermost primary optics 22a are directly connected to the confinement surface 102b. It is connected.

In contrast, the primary optic 12 is not directly connected to the confining surface 101a, rather the primary optic is connected to the confining surface 101a via a wedge-shaped contact element 240a. In the present example, the primary optical device 12 is connected, in addition to this second contact element 240b, with a second lateral limiting surface 101b.

In this case, the narrower wedge surface of the contact element contacts the primary optic 12, while the opposing wider wedge surface contacts the limiting surface 102a ( FIG. 6 ).

The contact elements are preferably formed of the same material as the fastening elements and the primary optics; Preferably the fastening element, the contact element and the primary optical device are formed integrally with each other.

It should be mentioned in this connection that, especially in the case of monolithic designs made of the same material, there is no limiting surface in the original material sense; this limiting surface is only an imaginary surface.

The use of such contact elements further contributes to the reduction of scattered light, since in this way the size of the area where the projection optics are connected to the holder can be kept small.

Finally, for example, between the two lighting units 10, 20 there is arranged a screen, in particular a wall-shaped screen 300, which is connected to the secondary optical device 31 from the fastening element 100. ) It can also be seen that it extends to .

One screen 300 or multiple screens 300 and the fastening element 100 preferably have upper and lower parts that can be inserted together, overlapping one another.

For example, the screen is in contact with the fastening element 100 , and as a result the light originating from the lighting unit cannot cross the gap between the screen and the fastening element and enter the interior of the adjacent lighting unit.

One or more screens run approximately parallel to the main light emission direction of adjacent lighting units, or parallel to each bisector of the main light emission direction of two adjacent lighting units.

The one or more screens are particularly flat and run substantially vertically.
